DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 421,432, dated February18,1890.

Application filed December 21, 1888- Serial No, 294,249- (No model.)

To all whom it may concern:

Be it known that 1, CHARLES W. RAYMOND, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in D umping Cars and Carts,of which the following is a full, clear, and exact description,referencebeing had to the accompanying drawings, forming part of thisspecification.

WVhile my invention is applicable to nearly all classes of dumping carsor carts, it is designed more particularly for tramway dumping-cars forconveying clay to pug-mills or coal to the top of inclined chutes orother dumping-point. Its novelty will be herein set forth, anddistinctly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a carembodying my invention and partly in section. Fig. 2 is a correspondingview of the car tilted asin the act of dumping. Fig. 3 is a detail frontelevation of the gate-latch. Fig. 4. is a detail rear elevation ofthe'car-body latch.

The same letters of reference are used to indicate identical parts inall the figures.

The truck A of the can maybe of the usual or any suitable construction,and it has upon each side a journal-standard B, to which, by means oftrunnions O, the car-body D is hung. The car-body is hung sufficientlyhigh above the truck to give the proper inclination in dumping; and whenin a horizontal ornornial position its rear cross-timber E rests upon acoincident timber or bolsterF upon the truck. A spring or weighted latchG, Figs. 1, 2, and i, is pivoted to the truck byjournals orboxes a andengages with a catch b, secured to the car-body-in this instance to thetimber E and serves to hold the car-body locked in its horizontalposition. A tripping arm c,-attached to or integral with the latch G,extends along one side of the truck, and is in this instance confined ina guide (Z and provided with the downwardly-bent elbow c andgrasping-handle f.

The end-gate II is hung, as at g, in the usual or any suitable manner-inthis instance by strap-hinges-upon a rod extending acrossuthe top of theear-body, and it is held locked, when the car-body is horizontahby apendent catch it, engaged by a spring or weighted latch I, Figs. 1, 2,and 3, pivoted to the under side of the car-body, as at 2', and providedwith a downward and rearwardly extending tripping-arm j, whose lower endis in close proximity to the forward crosstimber J of the truck.

One of the principal features of my invention consists in soconstructing and hanging the car-body that when loaded its center ofgravity will be on the dumping side of its pivotal support and whenempty it will be on the opposite side of said support, so that when thelatch which holds the loaded body in a horizontal position is releasedthe body will tilt to dump its lead, and when emptied will automaticallyreset itself to a horizontal posit on. This result maybe accomplishedina variety of ways by so constructing and arranging the pivotedcar-body that it is heavier on its side opposite the dumping side, buthas the greater part of its carrying-space on the dumping side of itspivotal support, so that when loaded the extra weight of the load on thedumping side will overcome the extra weight of the body on the oppositeside and shift the center of gravity to the dumping side; but whenemptied the center of gravity will shift back to the opposite side tocause the car to reset itself. The method I have illustrated foraccomplishing this result consistsin providing that side of the car-bodyopposite the dumping side with an inclined bottom K and arranging thepivotal support of the body on the dumping side of the center of thebody, as seen in Figs. 1 and 2. It results from this construction thatwhen the car-body is loaded the center of gravity is on the dumping sideof the pivotal support of the body, and that when empty it is 011 theopposite side of said support. As another method of accomplishing thesame result and dispensing with the inclined bot-tom, the pivotalsupport of the body might be moved to that side of the center oppositethe dumping side and that side he made heavier than the dumping side bymeans of weights or otherwise, which weights, when the body wasloaded,would be overcome by the extra weight of the greater part of theload on the dumping side of the piv otal support; or, instead of makingthe side opposite the (lumping side heavier, the car might be providedwith springs which would hold the body in a horizontal position whenempty, but whose pressure when the body was loaded would be overcome bythe greater weight of the load 011 the dumping side of the body. Iprefer the construction employing the inclined bottom, however, for thelatter facilitates the dumping of the'load when the car-body is tilted.

The operation of the car illustrated in Figs. 1 and 2 is as follows:Supposing the body to be loaded and locked in a horizontal position withits end-gate closed and latched, the car is moved by any suitable meansto the point where it is desired to dump its load, and the latchGisdisengaged from the catch 1), either by hand or automatically, by theshoulder e striking the stationary trip It and raising the tripping-armc. The car-body, being thus released, at once begins to tilt toward thedumping side, owing to the greater weight being on that side of itspivotal support, and the arm j of the latch I, coming in contact withthe cross-timber J,disengages the latch I from the gate-catch it, thusunlocking the gate H and permitting it to swing open as the body tiltsto the position shown in Fig. 2 to dump its load. As soon as the load isdischarged, that side of the body having the inclined bottom being 'nowbecome the heavier, the body tilts back and resets itself to ahorizontal position, the end-gate swinging in and becoming relocked andthe catch 1) engaging with the latch G, as will be readily understood.

It is of course obvious that the car-body may be hung so as to dumpsidewise instead of endwise, in which event the gate would gedupon theside instead of the end of the \Vhile I have shown and described my improved dumping-car as entirely automatic in the operation of all itsparts, and while for some purposes such construction is highlyadvantageous, yet it is not an essential feature of my invention thatall of the parts of the car should operate automatically. Thus in manycases there will be no necessity for automatically releasing the latchG, and in some instances this latch need not be arranged toautomatically lock the body when the latter is reset to its horizontalposition. Again, many features of the invention may be advantageouslyused in a dumping-car which is not arranged to automatically resetitself after dumping its load, as where the pivotal support is arrangedon that side of the center of the body opposite the dumping side, sothat when released the loaded body will tilt to dump its load, but willremain in tilted position until reset by hand. In such cases,especially, can the automatic locking feature of the latch Gr bedispensed with without seloaded, run out to the dumping-point withoutany attendant going with it, the body be automatically released by thestationary trip, tilted and its load dumped, and be pulled back to theloading-point in its tilted position and be there reset to and locked ina horizontal position by the attendants who load it.

In some instances the car-body may be of such construction that it needhave no endgate, and where an end-gate is employed the latch I, arrangedto automatically unlock it .when the body is tilted, may be employedwith advantage, whether the operation of the other parts of the car areautomatic or not.

Having thus fully described my invention, I claim- 1. In a dumping-car,the car-body pivoted between its ends, and having its side opposite thedumping side made heavier than the dumping side, and having the largerpart of its carrying-space on the dumping side of its pivotal support,whereby when the car is loaded its center of gravity will be on thedumping side of said support, and when empty it will be on the oppositeside of said support, substantially as and for the purpose described.
